A: Veil of the Void uses a custom six-sided die system that has been carefully crafted over 5 years time. Every roll in the game uses a six-sided die: everything from damage to skills.
A: The "*" signifies a unique ability or spell. This means that ONLY the class that the ability/spell is under may take that ability/spell. It cannot be used during custom classing unless a specific rule states otherwise. This also goes for Specializations. Unique specializations will always be marked with an "*" and any abilities in a non-unique specialization that has an "*" means they are unique to that Specialization.
